Hochiki CHQ-MRC2/DIN (HFP)-SCI Analog Addressable Main Relay Module Rail Type with Short Circuit Isolator

Hochiki CHQ-MRC2/DIN(SCI) module is an addressable module used in fire alarm systems.

Detailed Information

1. Two Relay Outputs

• Provides two independent relay outputs (Form C, SPDT).
• It can be used to control external devices (e.g. fans, doors, HVAC systems).

2. Addressable Technology

• With Dip-Switch on the module 
• This helps locate the fire quickly.

3. SCI (Short Circuit Isolator)

• The internal short circuit isolator prevents the spread of damage when a short circuit occurs in the circuit.
• It ensures that the rest of the system continues to operate in the event of a short circuit.

4. HFP (Hochiki Fire Protocol)

• It provides fast and reliable data communication using Hochiki's proprietary fire protocol.
• It improves the overall performance of the fire alarm system.

5. Easy Installation and Maintenance

• It has a compact design that can be mounted on a DIN rail.
• It can be easily installed and maintained with its user-friendly assembly and maintenance features.
